[1.] One line summary of the problem:
Kernel OOPS 'megasas_issue_blocked_abort_cmd' after a few thousand "scanning ..." lines
[2.] Full description of the problem/report:
If something on the scsi bus happens (or the kernel things that something happens) we get a few thousand "scanning ..." lines. After some time (between 30 min. and 5 hours) the 'scanning ...' stops with an kernel OOPS
[3.] Keywords (i.e., modules, networking, kernel):
megaraid, megasas, scanning, kernel, scsi
[4.] Kernel version (from /proc/version):
Linux version 2.6.33.2 (root@sd53) (gcc version 4.3.2 (Debian 4.3.2-1.1) ) #3 SMP Fri Apr 9 20:28:13 CEST 2010

[7.7.] Other information that might be relevant to the problem
(please look in /proc and include all information that you
think to be relevant):
[X.] Other notes, patches, fixes, workarounds:
I think the problem is the H700 controller in combination with the megasas-driver.
We have a lot more systems running 2.6.33.2 and only the servers with the H700 controller are giving this problem.
Also after some sime (after the scanning and oops) we experience user space freezes.
I tried 2.6.34 and give the same problem, only not the 'scanning-loop', just 1 'scanning-line'.
It's on a production server so I didn't test 2.6.35, can't reproduce it on a test machine.
Best Regards,
Reinier
